Question

which correctly lists three water sources that contribute to a river system?
○ groundwater, ponds, streams
○ lakes, rivers, ponds
○ rivers, streams, watersheds
○ streams, lakes, oceans

Explanation:

• Groundwater seeps into river systems, ponds drain into rivers, and streams are direct tributaries. Other options include either components of the river system (rivers, streams) or end destinations (oceans) rather than contributing sources, or non-source features (watersheds, which are drainage areas, not water sources).

Answer:

groundwater, ponds, streams
